Prestressed plastic corrugated pipe equipment Qingdao bamboo Cui first domestic manufacturing, from 1999 now has many years of production experience, advanced technology in the country come out on top! The bamboo prestressed plastic corrugated pipe equipment, mainly used for highway overpasses, viaducts, railway bridges and other concrete projects, the replacement of a different mold, can produce PP, PVC, EVA and other bamboo plastic bellows. A full bamboo prestressed plastic corrugated pipe equipment equipment by extruders, extrusion tooling, molding machine, sawing machine, reverse station or reel machine. Machine main gearbox, down template, transmission molding template, frame, air-cooled unit, composed around a mobile device, gear box using arc tooth worm gear reducer hardened, the template material for the HT150 down through the hollow casting, template Forced air cooled, the template is made of 40Cr heat-treated surface hardness HRC45-52, welded steel frame with high-quality, reasonably stable structure, the drive motor first with frequency converter, so as to achieve a uniform variable speed. Machine up and down, left and right, front and rear automatic adjustment. The prestressed plastic corrugated pipe equipment Main features: compact structure, stable operation, large carrying capacity, forced air cooled, high output, long life and other characteristics. Qingdao Cui biggest advantage; and material, speed, optimal production process recipes, incomparable. Mold specifications? 50-? 160? 110-? ??160 module number 4242 state single-wall single-walled tube drawing speed 0.5-3.5m / min 0.3-3m / min forming Cooling Water Cooling Water cooled water cooling pipe extrusion dies Cooling water-cooled water-cooled drive power 4KW 4KW unit mass 8000kg 8900kg Dimensions L * W * H (mm) 20000 * 1200 * 1950 20000 * 1300 * 1950 Supporting host SJ-65 single screw extruder SJ-90 single screw extruder corrugated plastic pipe and galvanized corrugated pipe performance comparison of the performance of corrugated plastic pipe corrosion resistance of galvanized corrugated polyethylene pipe is common plastics and chemical properties of the most stable one, Portland cement and water each mutual inert, and do not react, Well never rust galvanized rust resistance, but the reaction of the zinc coating is easy to grout base word and precipitation with hydrogen bond strength of the prestressing steel and concrete have an adverse effect under the circumstances aging durability cement seal package Time up to 50 years life in general in about 5 years minimum bend radius 0.9-1.5 (about 10-15 times the inside diameter or length axis) is greater than 30 times the inside diameter of the pipe, as the direction of the flat tube bending more than 30 times the major axis or minor axis partial load After loading resistance no leakage, no worries bent pipe leakage unrecoverable after deformation, water leakage resistance pipe wall thickness concentrated load after load of 1.5-2mm, into a single ring layout, stiffness, and are not afraid to step on the pressure can not easily be punctured pipe wall thickness vibrator is 0.2mm-0.4mm, into a spiral arrangement, the stiffness is relatively small, crushes deformation, pouring concrete vibrator can not touch the bellows pressure-resistant pipe sealing continuous extrusion No fracture pressure, humidity, humidity 20 degrees, under pressure 50kpa conditions, to maintain watertight pipe 24h 0.2-0.4 fold strip bite, that will be under no pressure leaks, there will seep under pressure coefficient of friction 0.14 0.25 insulating cement of non-conductive, adhesive plastic insulation, good conductivity and adhesion to concrete and concrete itself on superior adhesion to metal and concrete, while the higher corrugated plastic pipe, concrete and mechanical occlusion good because zinc the impact layer and the concrete bonding adhesive poor performance in general, and should be reduced to prevent corrosion and rust resistance, and adhesion to concrete
